TEST AND ADJUSTMENT
NOTE: Sensor has a 2 minute warm up period before it will
detect motion. When switching modes wait 2 minutes.
1. Slide the sensor switch to the TEST position.
2. Place the RANGE adjustment in the medium position (halfway
between MIN and MAX position).

3. Loosen the clamp screw in the sensor ball joint.

4. Walk through the coverage area noting when the lights turn on.
Gently move the sensor head up, down, or sideways to change
the coverage area. Note: Wait 5 to 10 seconds after light turns
off to retest.

5. Increase RANGE only as needed. A higher RANGE setting may
cause false triggering and reduce battery life.
6. Secure the sensor into position by tightening the clamp screw.
Do not overtighten the screw.
7. After dark, loosen the light joint clamps and adjust the light to
cover desired area. Tighten joint clamps when desired area is
covered.

Adjustment of Coverage Area
The sensor detects "motion" by the movement of heat (body heat)
across the coverage area. However, following are examples of
objects that also produce heat and can cause the sensor to false
trigger:
• Pools of Water
• Dryer Vents
• Heating Vents
If you suspect that a heat source of this type is falsely triggering
the sensor, try reducing the RANGE or aiming the sensor away
from the heat source in question.
Note: The detector is less sensitive to motion directly towards it
and more sensitive to across motion.
Motion
Least Sensitive
Place the sensor switch in the 1 or 5 minute mode for normal
operation. If the light is not needed, put the switch in the OFF
position.
Mode:
Test 5 Seconds
Auto
1 or 5 Minutes
IMPORTANT: To conserve battery power, this light has an
automatic dimming feature when using the 5 minute setting. After
all motion has stopped, the light will remain full bright for 2 ½
minutes. After 2 ½ minutes, the light will dim to about 1/3 power
180˚
for the remainder of the 5 minute timer.
